Hygger Aquarium Heater for Freshwater and Saltwater Fish (600W)

The aquarium heater features two safety mechanisms: an automatic power-off function and an audible alarm. The dual temperature probes built into the heating rod immediately detect when the water temperature exceeds 94°F (34°C), automatically stopping the heating to prevent the fish from being cooked. The controller will then display the "HH" error code and flash "Hi" to alert the owner.

Additionally, the low temperature protection function activates when the temperature probe detects the water temperature dropping below 59°F (15°C). In this case, the heater will automatically start heating, and the controller will sound an audible alarm and display the "LL" and flashing "Low" error codes until the water temperature exceeds 59°F.

The anti-dry operation function is another safety feature. When the heater's temperature sensor detects a low water level, the heater will automatically stop heating to avoid dry burning. The controller will then sound an alarm, display the "L1" error code, and flash "Auto Off." To avoid potential burns from the residual heat, it is recommended to unplug the power and allow the heating rod to cool down before removing it from the water when changing the water.

This aquarium heater is suitable for both freshwater and saltwater tanks, with wattage options ranging from 400W for 40-80 gallon tanks, 600W for 66-135 gallon tanks, 800W for 80-220 gallon tanks, and 1000W for 130-260 gallon tanks. The temperature control range is 59-90°F for all models.

The built-in dual temperature probes ensure safety by alternately measuring the temperature to prevent both overheating and overcooling, which could harm the fish. The audible alarm and automatic shut-off functions provide additional safety measures.

The company offers up to one year of after-sales support, promising to address any issues that may arise.

To choose the most suitable wattage, the formula is: (tank length x height x width) / 1000 x 2 = the required wattage.

The external digital controller features a high-definition LCD display that shows the current water temperature, set temperature, and heating status. The separation of the heater and controller enhances the waterproofing of the aquarium heater, and the temperature can be adjusted in either Fahrenheit or Celsius without the need to wet your hands.

This aquarium heater is designed for stable, fast, and even heat dissipation, utilizing a nickel-chromium electric heating wire, a thickened quartz glass explosion-proof tube for heat conduction, and an ABS plastic shell for protection. This setup ensures efficient and safe heating, reducing electricity bills in the long run.

Additionally, the heater features a memory function, allowing it to maintain the set temperature even after a power outage. It comes with three suction cups, a controller bracket, a hook, and a 10-foot external power cord for easy installation.
